The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
This version was released on June 30, 2006. On September 11, 2012, IBM extended the end of service for V6.1 by a full year, to September 30, 2013, and announced new version-to-version migration incentives and assistance. [27] It is a Java EE 1.4 compliant application server and includes the following function: Support for Java Standard Edition 1.5
SVC is a two byte instruction with the hexadecimal operation code 0A; the second byte of the instruction, the SVC number, indicates the specific request. [2] The SVC number can be any value from 0 to 255, with the particular SVC number being up to the implementer of the operating system, e.g. on IBM's MVS, SVC 3 is used to terminate a program, while on the UNIVAC VS/9 and Fujitsu BS2000 ...
Control Program Facility (CPF) is the operating system of the IBM System/38. [3] CPF represented an independendent line of development at IBM Rochester , and was unrelated to the earlier and more widely used System Support Program operating system.
HASP was developed by IBM Federal Systems Division contractors at the Johnson Space Center in Houston. [1] [2] It originally managed job scheduling and print and punch output for a single OS/360 computer. Multi Access Spool capability was added to let peer computers share a common job queue and print/punch output queues. [citation needed]
Rexx is a full language that can be used as a scripting, macro language, and application development language. It is often used for processing data and text and generating reports; this means that Rexx works well in Common Gateway Interface (CGI) programming and is used for this purpose, like later languages such as Perl .
The program status word [a] (PSW) is a register that performs the function of a status register and program counter, and sometimes more. The term is also applied to a copy of the PSW in storage. The term is also applied to a copy of the PSW in storage.
The Control Language (CL) is a scripting language originally created by IBM for the System/38 Control Program Facility [1] and later used in OS/400 (now known as IBM i). It bears a resemblance to the IBM Job Control Language and consists of a set of command objects (*CMD) used to invoke traditional programs or get help on what those programs do.
